Restart file write time bug?

Submitted by Jiri on Sun, 11/04/2018 - 00:42

I have problems with controling write interval of restart file during the simulation, I set a writeLiggghtsProps to write a restart file every cfd write step. The first restart file is created at writeIterval, however, after that there is created another restart file every single CFD time step.

I set writeInterval in controlDict to 1e-2s, CFD time step is 5e-5s. First file is correctly created: liggghts.restartCFDEM_0.01, however than a huge number of files is generated, liggghts.restartCFDEM_0.0100500, liggghts.restartCFDEM_0.010100 .. and so on, at next every CFD time step.

Do you have any idea what could cause that strange behaviour? Is it a bug in the CFD-DEM coupling? I use OF5 and current release of CFDEM and Liggghts.

Any answer would be helpful, thx.

Best regards,

Setting of my writeLiggghtsProps:
writeLast off;
//path "../DEM"; // optional setting
writeName "post/restart/liggghts.restartCFDEM";
overwrite off; //on;

Hi, Jiri.
Have you solved this problem? I met the same situation. I only want to save the restarDEM files as the same write time step as the CFD. While the DEM write the restar files as the every step of CFD. Large amounts of useless files are accumulated in DEM. Is there any setting or method to solve this problem?
